Most Bissell Proheat Carpet Cleaners have a small pump located in the front of the machine underneath the nozzle and a rectangular heater located inside the handle assembly. The most common cause we have found of them not spraying solution is due to the heater being plugged, followed by a broken or stretched pump belt and finally a defective pump.
Since changing the belt is the easiest fix, we suggest you check that first. (Before attempting any repair be sure your machine is unplugged from the electrical outlet). Most Proheat models have two belts; a cogged belt that turns the brush roll, and a flat belt that turns the pump. If the pump belt is stretched or broken it needs to be replaced. The pump and belts are located in the front of the machine on the operator’s left. Turn the machine over and you’ll see a red retainer with 2 screws. Remove the retainer to gain access to the pump and belts. While you’re there check the red pump pulley, it’s where the two belts are. If that pulley is broken or loose you’ll have to replace the whole pump, the pulley is not available separate.
Instructions Continue Below!
If the belts and pump pulley are OK check the heater next. The heater is rectangular and made of metal. It is located in the handle section. You’ll need to remove the screws from the back of the handle to gain access. (CAUTION: these heaters retain heat for a long time, make sure your machine has been off for at least 60 minutes before touching it!) Remove the tubing from the heater and also the heater cover. You’ll probably see sediment inside. Clean out any sediment you see and use a paper clip on the nipple connectors where the clear plastic tubing was attached to ensure they are not clogged. After reassembly, running some white vinegar through your machine may help to clean out any unflushed sediment.
If neither of the above solved your problem then the pump itself may be bad. You can usually get a new pump from your local Vac repair shop. We also have them available on our website at www.VacuumCleanerShop.com





I have a Bissell carpet shampooer. When I put the resevoir (containing hot water) on the shampooer, it will not spray out. It just pours out. What is wrong?
Question: I have a Bissle 9200-2 pro heat carpet cleaner and it wont spray water or soap, I have it apart and the pump seems good but there is an electric switch that directs flow from floor to hose, is it likely to be that.
Hi my proheat bissell 7901 stopped pumping water to the floor, but it pumps water from the hand hose. I read the manual and followed how to check belt and the flat belt on right side of shampooer is fine and I turned on and it turns and so do the brushes at the bottom of the machine. I was reading online and I guess there’s two belts on this machine? where can I find the other belt to see if it needs replacing. I guess it’s a ribbed belt? that is the water pump belt?
To Laura: The ribbed belt is the one that turns the brushes. If your brushes are turning then the belt is fine. However if you want to look at it. There are two screws on the bottom near the brush head (back a few inches from each end of the brush) that can be remove to pull the brush assembly out. You really shouldn’t need to do this unless the brush is not rotating.
had to replace the pump, but now I can’t the mixture right. It will spry soap but not water. I don’t know how to correct this.I guess I have something on wrong for the mixture but I can’t figure out what.
Machine will not spray soap from brush head or cleaning attachment. Sprays only water.
machine will have sucktion with attachment but no water or soap goes on floor i cant figure it out the belts are fine what else could it be?
I had the problem of water/soap not spraying out. The issue in my case was two fold:
1. You need to give the vacuum some time after turning it on before pulling the spray trigger. When you turn the vacuum on, the pump initially needs to get a good “prime” and work any air out.
2. Gaskets: On the bottom of the fill container is a red gasket. For me, that gasket was not on correctly, and thus I wasn’t getting a good seal.
If you do take yours apart, be carefult to (a) take note of where all the hoses go before removing them, and (b) be aware that if you may dislodge some air gaskets that can cause a loss of air suction. The gasket can be easily reseated from the underneath panel.

One last and very important thing to check (after you clear out the tube’s) the HEATER itself. In my case the heater inlet and outlet were CLOOOOOOOOOOOOGED. Cleaned it out, put it back together, and…………. it worked……….. Thanks for a starting point………………
this is the third one iv bought in three years and they all do the same thing after u switch from floor to tools they do not work again i can not get it to switch back to floor it will not spary the water or fluid at all. I will never buy another one again. the money i spent on one i should just go rent a carpet cleaner and save myself 200.00 every time i want to clean carpets
i have a bissell pro heat 2X and no water or solution will not spray out
I have a Bissell Proheat 25A3. It has stopped spraying. I have checked the belts. I have checked the heater for clogs. I have checked the lines for clogs. The brushes are still turning. It still has suction. I have checked the motor thinking it may have a clog. I even took apart the pump as much as I could to clean it out. Nothing has helped. Any Suggestions?
I have a Bissell Proheat Pet and I cleaned my carpet and it worked fine although I noticed it started making a loud noise when I flipped it to heavy traffic. After cleaning the carpet I turned it off and switched to hand tool and it worked for about 5 minutes then stopped spraying and smelled like it was burning. This is my mothers brand new carpet cleaner and I really don’t want it to be broken. Please Help!
This seems to be an on going problem I have replaced the pump it will pump water until I select to use cleaner solution than nothing from hand held or brush area. any suggestions? all tubes and air vents are clear.
I borrowed one from a friend and they use it all the time. When i used it it wasnt doing anything at first. I unscrewed everything and checked for clogs and there wasnt any so i screwed it back together still nothing pulled the reservoirs off checked them emptied them filled them back up still nothing. then i unscrewed everything again and checked the pumps didnt pull anything out i moved the soap pump like a millimeter pushed it back down to its spot and screwed it back together and all of a sudden it started putting soap on the carpet. Although i still think there is something wrong with it the bladder wasnt getting any emptier while i was using it so i think the pump for that is bad and i cleaned the carpet with just the soap formula and it did an amazing job. I took about 7 hours to clean (and dismantle and re-mantle the cleaner) my studio apartment got all the stains out and my carpet looks and feels clean
Bissell needs to recall this product! Everyone has the same problem. After paying over $200 for the “better” carpet cleaner (Bissell Pro-Heat, Self-propelled), it stops working correctly after only a couple uses! The spray stops coming out either from the floor setting or the tools setting, or in my case, both! What really makes you mad, is that you don’t know it until after you think you’ve cleaned 1/2 the room! This is a defect that Bissell should recall, as we are all out the money we paid! I contacted Bissell and they were of no help at all, except for trying to trouble-shoot the problem over the phone with idiotic solutions that didn’t work. No more Bissell products for me unless a recall is issued to all of us who have been screwed!
oh, and watch the government BAIL OUT The company with out tax dollars when they go broke from lack of new business! Only in the U.S.A.
